Question

What is code P1774 for a 2007 Nissan Frontier V6?

Answer 1

Hi there

This code is for the low coast brake solenoid function. This is inside the transmission and connected to the valve body. The cause could be an electrical issue or some kind of problem with the solenoid itself. Also, check the transmission fluid level and make sure it's clean as well.
